TYPE-WRITING MACHINE Patented Aug. 5, 1919.

Original application filed January 22, 1915, Serial No. 3,691. Dividedand this application filed December 21, 1916. Serial No. 138,159.

To all whom it may concern Be it known that we, EDWARD THOMAS andBURNHAM C. STICKNEY, both citizens of the United States, said THOMASresiding in New York city, county and State of New York,

and said STICKNEY residing in Elizabeth, county of Union, and State ofNew Jersey, have invented certain new and useful Improvements inType-Writing Machines, of which the following is a specification.

This invention relates to typewriting machines and more particularly tomeans for controlling the character of the printing.

In practice, it; is sometimes desired to have the writing in certairfcolumns .charac teristically distinguished from that done in othercolumns. This may be done by writing the characters with types of difforchanging the character of printing is preferably connected to thecolumn-selecting keys to be operated thereby.

The typewriter carriage, however, may be fed into the special zone inwhich-the distinctive printing is desired by its ordinary escapementmechanism, or otherwise than by tabulating. As it is sometimes desiredto determine whether the carriage entered the special zone by thecolumn-selecting mechanism, or by the escapement mechanism orotherwise,we provide mechanism which will cause the printing in the specialcolumn,

when the carriage is thus positioned, to be distinctive not only fromthe ordinary work but also from the work which is done in the specialcolumn, when the carriage is located therein by the column-selectingmechanism.

In the present disclosure of our invention, we utilize the case-shiftmechanism of the ordinary machine to change the character of printing inthe special zone, when the pose, the upper set of types on the type-barsare of different size or conformation from those of the lower set oftypes.

This utilization of the case-shift may be effected by providing a bailhaving connections to a cam arm, which, when operated, engages andoperates the case-shifting mechanism of the typewriting machine. Thisbail may be operated by an interponent arranged on the operatedcolumn-selecting key, which interponent may be moved into and out ofcooperation with the bail at will, by means of a revolu'ble cap on theforward end of the key lever. These capsv may be set to proper positionby the operator, according to the nature of the work to be done. A lockmay be provided for automatically holding the platen shifted or in itsupper-case position.

- In providing for the additional distinctive printing while' thecarriage is in the special zone, after being. ositioned there bytheordinary letter-fee ing escapement, we have found it convenient toutilize the bichrome ribbon-shift pf the machine, so as to change thecolor of the printing. The bichrome ribbon usually comprises twodistinctive colors, one of which is usually red and the other black.This bichrome shift maybe controlled by a lug settable along thecarriage; and this lug may be part 0 the usual tabulator stop.

In order not to burden the typewriter carriage with the actual operationof the rib bon-shifting mechanism, and in case the typewriter carriageshould pass the special zone without any printing being done therein, wehave provided mechanism, whereby the carriage simply positions certainmecha nism, which causes the shifting operation to take place, when thetype keys are operated to rint. This mechanism may comprise a baiextending across the entire zone, and adapted to be operated by a lug ona tabulator stop used'to locate the carriage in the special zone.Connected to this bail by suitable mechanism, may be provided aninterponent in the form of a universal member, which is moved by theoperationof the bail beneath the type key levers of the machine.

In the usual Underwood typewriting machine, alphabet keys 1 and numeralkeys 2 depress levers 3 to rock bell cranks 4 which are connected toswing type-bars 5 upwardly and rearwardly against the front side of aplaten 6, mounted in a carriage 7. The carriage 7 travels step bystep ateach depression of a numeral key by means of the usual escapement dogs8and 9, which are effective on the usual escapement wheel 10 permittingthe carriage to be drawn forward by a sprin barrel, not shown herein.The carriage 1s controlled by said esoapement wheel through a rackllfivingableon said carriage, but normally meshing with a pinion 12-connected with said escapement wheel.

To permit said escapement wheel to turn,

the dogs Sand 9 are rocked at each depres.- sion of a numeral key, bymeans of a uniplaten. In addition-to the above-described forward letterfeed of the carriage, the Underwood typewriting machine usually includesa tabulating mechanism for rapidly positioning the typewriter carriageat any one of a number of selected letter-spaces. For this purpose, themachine is provided with decimal tabulating keys 15 mounted on the frontends of key levers 16, pivoted at 17, so that when any one of said keysis de- In the present machine, the mechanism is somewhat modified fromthe usual Underwood mechanism and is of the general type illustrated inthe patent to VVernery, No. 1,108,415, August 25, 1914-, and illustratedmore in detail in the co-pending application No; 782,391, filed Aumechanism illustrated 1n said patent and application, thecolumn stop bar21 is normally raised so as to hold its stops 20 out of the reach of thecounter-stops 19 even when a counter-stop is pro'ected, as abovedescribed; the rack bar or this purpose comprisirfg arms 22 which arepivoted at 23- on st 1, 1913. In the the typewriter carriage, thuspermitting a spring 24 to normally hold said rack bar in' its elevatedposition. 7

Whenever it is desired to perform the tab ulating operation, it isnecessary in the present disclosure of the invention to depress both adecimal tabulating key- 15 and a column-selecting key 25,- and theconnections are such that whenever a column-selecting key is depressed,the rack bar 21 willbe swung downwardly when the column stop 20 thereonapproaches the proper column, with the resultthat the stop20 then liesin the path of the elevated counter-stop 19. In other words, the zone inwhich the tabulating is to be done must be first determined by thecolumn-selecting'key 25 and then the particular letter-space in saidzone is determined by the decimal tabulating key 15, which in themeantime,- has been depressed. In order to bring about this result, thecolumn-selecting keys 25 are effective to depress the rack bar 21 onlywhen said rack bar has brought the stop thereon approximately to thebeginning of the desired zone or column. c

To accomplish this, the column-selecting keys 25 which are mountd on thefront ends of key levers 26, pivoted at 27, raise at their rear ends,column-selecting bars 28, which normally are ineffective on the rack bar21, but which are each adapted to tension their own springs 29, with theresult that when the stop 20 arrives at the proper column, the spring 29which is tensioned by its columnselecting key, will depress the. rackbar 21, this being accomplished through connections to be describedpresently in detail, but which include a lever 30 comprising a roller31, rolling on the top of a plate 32, fast to said column stop rack bar21. Whenever a spring 29 is thus tensioned, it tends to raise a slide 33on its bar 28 and as soon as it can raise said slide, the slide willrock the range of any elevated counter-stop 19 andthus the firstcolumn-stop 20 would arrest the typewriter carriage by colliding withthe elevated counter-stop 19.

In order to prevent this, the column-stops 20 are adapted to operate aslidable locking bar 38 which prevents any slide 33 from prematurelybecoming efiective t-o'move the column-stops 20 within the range of thecounter-stops 19. Thisslidable locking bar is mounted in brackets 39 andis normally at rest. It, however, is moved along one step whenever anycolumn stop 20 passes the array of decimal tabulating counter-stops 19,and for this purpose, the column-stops 20, as they pass said array ofcounter-stops, are adapted one after another, to hit and turn to theextent of one tooth, a slide-operating wheel 40, which therefore movessaid slidable locking bar one step whenever one of said column-stops 20passes said array of decimal stops 1 To do this, the wheel 40 is fast ona shaft j'ournaled in an extension of the framework 41 in which thecounter-stops are mounted, said shaft carrying at its opposite end, apinion 42 meshing with a rackbar forming part of the slidable lockingbar 38. This slidable locking bar comprises, as disclosed in theaforesaid application and patent, a shelf which normally overlies thelugs 43, there being one lug 43 on each slide 33.. The shelf however, isinterrupted at one point, or provided with a notch so that whenever theslidable locking bar 38. occupies an appropriate position, it willpermit one of the lugs 43 to slide upwardly through said notch, andtherefore will permit the slide 33 of which'said lug forms a part, to bedrawn upwardly by its spring 29 and become elfec five on the bail 34,and thereby depress the rack bar 21, with the result that the columnstop20, at that moment approaching the decimal counter-stop 19, is depressedenough to be intercepted by the counter-stop 19. This permitsthecarriage to be arrested at the zone which has been selected by thecolumn-selecting key 25 depressed at the moment because anycolumn-selecting key 25 tensions only its own spring 29.

In order to prevent any column-selecting .key from being depressed afterthe type-- writer carriage has passed the Zone, in which sa d key issupposed to be effective, the bar 28, operated by said key, is providedwith a locking lug 44, which however is normally free to be elevatedupward. When, however, the typewriter carriage has passed the zone inwhich any given column-selecting key 2-5, is to be effective, thelocking lug 44 belonging to that key, is prevented from being movedupwardly, because the slidable lock-- ing bar 38 has, in moving along,carried a shelf 45, forming part of said slidable bar, above the lug 44aforesaid, thus completely blocking the column-selecting key 25 untilthe typewriter carriage is returned to a point which moves the aforesaidlocking bar 38 to a point where it clears said locking lug 44.

' In order to prevent the typewriter carriage from being released fromits escapement mechanism to travel to a new column before anycolumn-selecting key is depressed, the decimal tabulating keys 15'operate the usual carriage-release mechanism (described below) but arenormally held locked against being depressed by a swinging bail 46,which underlies ears 47 projecting upwardly from the levers 16 of saidkeys. This swinging bail 46 normally holds said key levers locked,because a spring 48 holds it rearwardly under the overlying upper partsof the ears 47. When, however, any column-selecting key 25 is depressed,said bail 46 is swung to ineffective position by means of an upward yextending follower 49 on the key lever 26 of the column-selecting key,and said ear cams the rocking bail 46 forwardly clear of the ears 47.thereby freeing all the decimal. tabulating keys 15. The carriage 7 isfreed from' the escapement mechanism in the usual manner when any one ofthe 'decimal selecting keys 15 is depressed. For this purpose, theplungers 18 are provided with shelves 50 effective on a short universalbar 51 pivoted at 52, so that when any plunger 18 is lifted, the rearend 53 of said universal bar draws down on a link 54, thereby drawingdown the rearendof a lever 55, so that the front end of said lever willlift the rack bar 11 off the escapement pinion 12 by means of an idlewheel 56, which runs on the lower side of said rack bar.

i In the usual case-shift mechanism of the Underwood typewritingmachine, the platen 6 forms part of. the usual shift frame, whichcomprises a roller 57, riding on a rail 58, forming part of a bell crank59 pivoted at 60 at the rear of the machine. This bell crank 59 may beshifted as in the usual machine, by case-shift keys 61 at the front endof key levers 62, which havev at their rear ends upwardly extending arms63, adapted to bear against the rear side ofthe lower ends 64 of thebell crank 59. Since the platen and shift keys are pivoted at their rearends at 65, depression of the shift key will raise keys are eachprovided with ha revoluble the bell crank 59, thus lifting the platenframewith its platen to upper-case position, in which position theupper-case types (see Fig. 2) are effective to print through the ribbonwhich passes through the vibrator 66,

instead of the lower-case types which usually print therethrough. Theplaten is held in this shifted position by a latch 66*, pivoted to themachine and provided with a spring 67, which, when the shift key 61 isdepressed, is adapted to move said latch 66*, so as to overlie a pin 68on the shift key and 'hold said key depressed. The latch 66 may bereleased to permit the platen to return to lower-case position, bymanipulation of ahandle 69, formed on the latch 66*, so as to disengagethe latch 66 -from the pin 68 on the key lever.

To automatically shift the platen when the carriage is brought to theproper column bythe column-selecting keys 25, said along the rear endsof the key levers 26 of the column selecting keys 25, and are adapted tooccupy either a forward ineffective position or a rearward effectiveposition, acggrding to the position of the revoluble head So that theoperator may readily setthese heads 70, each of the heads is providedwlth a window or opening 70 through which either the indications A or Bmay be seen, according to the position of the head. When the character Ais visible, the

'key will not automatically shift the platen when operated, but when theB is visible the interponent 73 is in position to cause thecolumn-selecting key 25, to automatically shift the platen whendepressed. The operator may therefore, by revolving the head '70 toeither position A or position B, de-

termine whether or not the column-selecting keys, for each individualcolumn, shall automatically shift the platen to upper-case position whensaid keys are used to locate the position.

When the column selecting key 25 is deprewed and rocked about its pivot27, andv the interponent 73. thereon is in effective position, theupward movement thereof, causes the interponent to strike and lift abail 74, overlying the interponents and fast to a rock shaft 75journaled in the frame of the machine. Secured to the rock shaft 75 isan arm 76, which is moved downwardly when said shaft is rocked. This arm76 is connected by a link 77 to a bell crank 78,

having an arm 79 engaging with the arm .63 of the shift key lever 62 ofthe usual Underwood typewriting machine. As the link 77 is drawndownwardly, by the upward movement of the bail 74 caused by theinterponent 73, the arm 79, of the bell crank .78, engages the arm 63,of the shift key lever, and operates the case-shift mechanism, causingthe platen to be shifted to upper-case position. The arm 63 thus beingmoved, causes the forward end of the shift key lever 62 to be depressedand locked in depressed position by the pin 68 thereon engaging with thelatch 6.6.

If after having shifted the platen automatically when positioning thecarriage by the column-selecting keys, the operator for some reason,desires to print the same form of characters as in other columns, thelatch 66 may be manually moved by the handle 69, to free the pin 68therefrom thus permitting the shift key lever 62 with the platen, toreturn to normal lower-case position.

According to the present invention, the character of printing ischanged, even though the carriage has been positioned in the specialzone by other means than the column-selecting keys, and when sopositioned, the character of printing is entirely distinctive from thatdone in other columns, and also from that done in the special column,when the carriage is positioned by the column-selecting means. For thispurpose, we have found it convenient to utilize the-usual bichromeribbon mechanism of the Underwood typewriting machine to change thecolor of the printing. Said bichrome mechanism includes the usual ribbonvibrator 66 through which the bichrome ribbon is threaded at the top,said bichrome being actuated by a lever 81. This lever is adapted to begiven various throws, according to the color of printingdesired, and thecolor of the printing is varied by the fact I that the top of theribbon, for example, as

shown in Fig. 9, may be black, whereas thebottom of the ribbon may bered. Thus a small throw of the lever 81 will cause black printing, and alarger throw willcause red printing. The varying throw of the lever 81is obtained by the usual'bichrome actu- "ator of the Underwood machine,said actuator being in the form of an open box, best shown in Fig. 9, ascomprising a rear slde 82, a black printing side'83, and a red prlntingside 84. This actuator as usual, is mounted on the universal bar orframe 13, at the rear end thereof, and is shiftablesidewise on saidframe by means of a link 85, for the purpose of bringing either the side83 or the side 84 in engagement with one or the other of actuating. pins86 and 87. The side 83 has a' slot in it in which the pin 86 can work,and since said pin is remote from a pivot 88 about which the lever 81works, said pin will give. said lever 81 a comparatively small throw.The shape of this slot is best shown in Fig. 7 where it appears that theslotis vertical, and that its sides fit the pin 86 closely. The side 84of the actuator box has a somewhat similar slot which actuates the pin87, and since said pin is comparatively near the pivot 88 of the lever81, it will give said lever 81 a comparatively J column-stops 20 of thetypewriter, since these 4 some machines for said purpose.

stops are customarily used for selecting the special zone, and in thepresent invention are used to an even greater extent" than in Thecolumn-stops arev effective to determine whether the machine shall writein red or black, by means of an'arm- 89 pivoted at the rear of themachine, on which arm they are effective through a cam 90 fast on saidarm. The arrangement of the column-stopsQO and the cam '90 is such thatif no column-selecting 1 key 25 has been depressed, the column-stop 20,as it travels along with the typewriter carriage, will engage (seeFig. 1) and cam outwardly (see Fig. 7) the cam 90, with the result thatthe arm 89 on which said cam is fast, is swung rearwardly and rocks its--color control shaft 91.

black in any column, whereas the numeral Fast on this shaft 91 is a'rock'arm 92, which has pivoted upon its depending lower end a forwardlyextending cam-operating link 93. This link operates a cam for thepurpose of compelling the.keys, when said cam is in its effectiveposition, to shift the ribbon so that the printing. will be done in red.This is effected by putting a ribbonshifting member 94 under the keys ofthe typewriter,'which is adapted to shift the above-described actuator82 from itsnormal black-printing position to a position in which itcauses the printing to take placein red. It will'be noted that theconnectionsmay be such that this ribbon-shiftingmember 94 is operatedonly by the numeral keys of the typewriter, with the result that thealphabet keys of thetypewriter may write keys are compelled to write redin a special column when the column selecting keys have not beenoperated. 4 r This rib on-shifting member-94 1s 1n the the numeral keys.

7 chine.

form of a bail having upstanding arms 95, one of which is adapted to lieunder every numeral key, the intervening spaces being left for theoperation of the, alphabet keys of the typewriter. The bail 94 issplined on a transverse rock shaft 96, and is normally drawn by a spring97 in such a way that the upstanding arms 95 are clear of the numeralkeys of the typewriter. When, however, a column-selectlng stop 20strikes the cam 90, as described above, so-as to shove the camoperatinglink 93 forward, the link carries its cam 98 forward, so as to thrustthe bail 94 sidewise by a pin 99 fast thereon. This thrusts said bail,94 so that the arms 95 thereon are in their effective ositions underWith t e parts positioned thus, every time a numeral key is depressed,it will rock said bail 94 and the shaft 96 on which the bail is mounted.

When the shaft 96 is so rocked, a rock arm 100 thereon draws down a link101 attached to a rock arm 102 on the usual color-control shaft 103 ofthe Underwood typewriting ma- This color-control shaft includes theusual rock arm 104, to which is pivoted the actuator shifting link 85,and this link, when shifted to the right, as seen in Fig. 9, causes themachine to write inred. p p The link is normally thrust to the left by aspring 105 coiled around the shaft 103, and shown in Fig. 6. Theseconnections are such, therefore, that the ribbon connections normallystand so that they will print-in black, but whenever a numeral key isoperated, the ribbon shifts to red, if the cam 90. engages thec0lumn-stop'20. The color-control shaft 103 maybe extended in front ofthe frame of the typewriting machine, in

order to enable the operative to control the color manually, and may beprovided with a suitable key 106, whereby the ribbon may-be held down toprint red when it would otherwise print black. In order that the keysneed not print red in a special zone, the cam is so placed that when acolumn-selecting key swings the rack bar 21 downwardly, it carries everycolumn-stop 20 thereon below idle, and the connections between the keysand the color shift are ineffective.

In order to make the equipment of the machine assimple as possible, thecolumn-stops 20 may have their sides of two forms, or be unsymmetrical,as seen in Fig. 1, etc., one side being cut away as seen at 107 (seeFlg. 4). When this cut-away side is uppermost, the cam 90 is alwaysentirely out of reach of the column-stops, so that the machine, then,will write normally in black in every colthe level of the cam 90, sothatsaid cam is umn, or in any column in which the columnstop 20 isappropriately set.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
